IMPROVEMENT IN THE CONSTRUCTION OF QOOKING'STOVES WITH DOUBLEFIRE-PLACES.

To all whom it may concern.-

Be it known that I, REUBEN JACKSON, of Zanesville, in the county ofMuskingum and State of Ohio, have invented a new and useful Improvementin a Cooking-Stove designed for Burning .Ooal; and I hereby declare thefollowing to be a full and exact description thereof.

The nature of my invention consists in the construction of an ovenbetween two fireplaces in such a manner that the draft of one firepasses over the oven and that of the other under the oven into thechimney, separate fines and outlets being used, as herein set forth.

To enable others skilled in the art to make and use my invention, I willproceed to describe its operation.

In order to produce an equal degree of heat on each side of the oven, Iconstruct my'stove in the form of an oblong square with one enddepressed about three inches,with a grate and fire-place at each end, asseen at Z, Figures 1, 2, 4, and 5, and the oven between the two fires,as seen at I, Fig. l and n, Figs. 4 and 5, with separate passagesthrough the stove for the escape of the smoke of the respective fires.The fire and smoke of one endviz., Z 2', Fig. 4are drawn upward over theoven, escaping through the flueviz., Fig. 4 p and Fig. 2 Jwhich heatsthe side of the oven next to the fire and the topof the oven. The otherend of the stove d, g, Fig.- 4, and Y, Fig. 2, is depressed, so as tobring the top on a level with the oven, which entirely closes the.

passage upward and prevents the two fires from coming in contact. Thefire from the grate Z, Figs. 2 and 4, passes over the plate E, Fig. 4,down the plate 01 and escapes through the flue at r, Fig. 4, and B, Fig.2.

In order to regulate the heat I construct two fiuesviz., C C, Fig. 2,and 0 q, Fig. 4with dampers consisting of small plates sliding over theplate X, Fig. 4, which are drawn out horizontally, as occasion requires,by rods attached to them and running through the end plates of thestove, as shown at D, Figs. 1 and 2, and A A, Fig. 4. When these dampersare drawn, a portion of the heat escapes through the apertures 0 q, Fig.4. The draft of the fires is regulated by a plateviz., J J, Fig. 2ofsufficient width to fill the apertures a B, Fig. 2; but as this is notpatentable a further description is unnecessary. The sides of the ovenconsist of two plates, as seen at a b, and c and 61, Figs. 4 and 5, withsmall holes through the side plate, Fig. 4, x 00, through which the aircirculates, by means of which the plates in contact with the fire areprevented from consuming and the oven from becoming too hot. The topplateviz., Figs. 1 and 2I construct with any number'of depressions abouttwo inches in depth, into which any cooking utensil may be placedwithout coming in, contact with the fire and smoke. I also constructsmall feeding-doors viz., Figs. 1 and 2, K K-above the principal ones,into which coal may be introduced without the egress of smoke.

- In order to clean out both the stove and the pipes, I make an openingin the front plate,

as shown at H H, Fig. 1, into'which a scraper of one fire shall passover the oven and that of the other under the oven into the chimney,separate lines and outlets being used for that purpose, as herein setforth.

REUBEN JACKSON.
